The author focuses on the importance of the body in the analysis of patients with a defect of thinking. In many cases this defect is not fully evident until concrete and bodily aspects begin to emerge in sessions. In the absence of awareness of the body, the patient's personality is deprived of the main source of emotional stimulus, and mental growth is consequently paralysed. Hence the body is considered the starting point of mental processes and a progressive source of experience requiring the exercise of responsibility and thought. To indicate the theoretical background to this essentially clinical paper, some hypotheses about the body– mind link are very briefly considered. Specific emphasis is given to the development of Freud–Klein–Bionian theories about this subject and to some of Ferrari's recent proposals. The author discusses four clinical cases, emphasizing the encounter with the body in analysis and its integration in emotional and thinking processes. The analyst's function in such cases is conceived mainly as that of midwife for a dialogue between the analysand's body and mind.
